William B. McKinnon, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, led one of three new studies that together provide a far more complete picture of the composition and origin of Arrokoth. The new research published in Science points to the resolution of a longstanding scientific controversy about how such primitive planetary building blocks called planetesimals were formed.
Bhupal Dev, assistant professor of physics in Arts & Sciences at Washington University in St. Louis, proposes a new way to leverage data from ultra-high energy neutrinos from large neutrino telescopes such as the IceCube Neutrino Observatory in Antarctica.
Presolar grains — tiny bits of solid interstellar material formed before the sun was born — are sometimes found in primitive meteorites. But a noble gas analysis from physicists in Arts & Sciences reveals evidence of presolar grains in part of a meteorite where they are not expected to be found.
A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch.
A team of Washington University in St. Louis scientists at McMurdo Station, Antarctica, successfully launched its SuperTIGER (Super Trans-Iron Galactic Element Recorder) instrument, which is used to study the origin of cosmic rays.
Nobel laureate Kip Thorne will visit Washington University to deliver a public talk on Thursday, Nov. 7. Thorne’s work in theoretical physics examines gravitational waves, the Big Bang and what these phenomena tell us about the dynamics of the universe.
Richard Alley, the Evan Pugh Professor of Geosciences at Pennsylvania State University, will deliver the McDonnell Distinguished Lecture on March 6 at Washington University in St. Louis. Alley’s lecture is titled “Finding the Good News on Energy and Environment.”
S. George Philander, one of the world’s leading experts on climate and the interactions between the ocean and atmosphere, will deliver two talks March 28 and 29 as part of the McDonnell Distinguished Lecture Series, sponsored by Washington University in St. Louis’ McDonnell Center for the Space Sciences.
William B. McKinnon, professor of earth and planetary sciences in Arts & Sciences, will deliver the McDonnell Distinguished Lecture on Wednesday, March 29, on the Danforth Campus of Washington University in St. Louis.
Ernst K. Zinner, PhD, research professor emeritus of physics and earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, died Thursday, July 30, of medical complications of mantle cell lymphoma. Among many other accomplishments, in 1987 Zinner identified for the first time material in the laboratory that predated the formation of the solar system 4.6 billion years ago.
